4 Application filed April 29, 1826. Serial No. 105,539.

My invention relates to and has purpose the provision of a measuring device which embodies the combination of a tape measure and an extensible rule structure in such manner that the rule structure i ure linear form,

any-selected length and in whereby a correct measuring and reading can beconveniently and quick y ecured.

I will described only'on-e form or measuring device embodying my invention andvwill then point out the novel features thereciin claims.

j Inthe accompanying drawings,

Figure 1 is'a view showingin side eleva tion one form of measuring device embody ing my invention' in partly-1extended position; -11 c Figure 2 is a View showing in top plan the measuring device in folded position;

Figure 3 is a longitudinal sectional view taken on the line 8'3ot Figure 2. I

Figure l is a fragmentary sectional view showing the confronting ends 0:6 two tape supporting sections of the device and the corresponding latch.

formed with a. slot 22 through which the A tape is adapted to move and from which a portion of the tape is at all times extended.

For supporting the steel tape in linear form and in any selected length, I utilize the conventional structure of an eittensible rule This structure is here terinec an extensible support and comprises a plurality of linear sections 23 formed of wood or other suitable material superimposed when in folded position as shownin Figure 3, and

, interlatched at their ends by latching devices 24:. The lowermos u section is permanently secured within the frame by screws or rivets 25, but the other sections extensible one up0n;the other and slidably connected hy brackets 26. When any one section s in tor its they ar tally extended posit aldgacent section, the latching devices funca cronto rcleasably lock the first section in i v. "tr"|dj1 0;" I rall or cnocc position. 'lhe latching devices are ot the conventional type used in extensible rulers as illustrated in Figure l'to permit sliding of one section upon the other and to latch a section intully extended posi- 111011 on an ad acent section. To release the device in folding". a section upon another it is only iecessary to depress a latching finger when the section can he slid inwardly on an adjacent section. s v i The uppermost section 23 has secured to means of a screw or other, fastening member TO'lllfllntfill-fl the tape in operative engagement vith thesnpporting sections as moved to extended position, I provide a plurality of brackets 28 having slots 29 through which the tape 21 extends, in amanner to prevent sagging of the tape and to thus hold it in line. By reference to Figare it will be seen that the severalbrackets are dusted in length, with the uppermost bracket seciired to the inner end of that sec tion 23 which is third from the'topmos't section, while the remaining brackets-are secured to every other section 23.

In order to etiect a correct reading, the

tape 21 is adapted to be engaged by a clampiinger 80 secured to a pintle 31 journaled in the parallelpor tions 'l5 and 16 and get its outer end'an arm 32 disposed orlv of the frame and manually opers ion with respect to 7 an 7 4 its outer end the free end 01" the tape 21 by ableto move the tinger30 against a cross bar v 83 seciired in the frame so that the tape will i 'sed against the crossbar and areadr the tape at that pointinter?- y the forwardedge of the cross bar. In practice, the supporting sections 23 can be successively eatended fro a the, frame by outwardly upon-the sections "and eby unwinding the tape 21 with the lati the openings 29 of the idingi'thro hrac ets. In measuring the openingsof bnildnigs'ifor screens, 'or'fin, any other. use, the device is placed in the opening with the frame projections andlSin contact with one wall of the opening. The supporting sections may now be extended until the right hand end oi'the topmost section contacts with the opposite wall of the opening when the distancebetween the two walls can be accurately determined by the reading given upon the tape 21 at the point where the forard edge of the cross bar 33 intorseets the tape. It in to be particularly noted that the free end ot the tape 2]. begin-,1 with a reading of 3 inches, in order to eonipenaute tor the distant-o hetu'oen the it'orivard edge of the Cross bar 33 and the lett hand vortieai edge of the 'tralne proieetions it? and 18; thus the reading at the forward edge (lit the ore bar will be correct.

It \vili he understood that in order to restore the supporting nemionn to toldeq pin-it-ion, as shown in liinnre l. it will he net-o sary to first. relea -1e the latrhingr devires: llfor ttlt'll oi the :wrtionu. and when niovi' 5 the sections to tolded po.--ition the spriusi' drum automatically reu'inds tho tape Within the easing .19.

My invention. aithouejh employing); the strueture of o ermventiouai extensible rule, possesses the important advrn any of arenrately in insuring diotanres: ot or hetween ohjeets in eontradistinetion to the ordiuanv em tensihle rule. This: in due to the tan-l; that it is unnee 'iary to tally extend earl! and every section. as is IYEtCQFStU'V with the conventional rule, in order to Feeuie an aerurate measurw ITIGITt lJOCHUSG the measuring; tape deteriniuru the reading and not the tift'ilhlm upon the Few-- tions of the rule, it being noted that l have omitted from the Rupportiinr sections the measuring numerals.

Although I have herein shown and di seribed only one torni of measuringdevire embodying my invention, it in to be under stood that variom ehan i'es and inoditiii'ution?v may be made therein without departing l roiu the Spirit of the ii'nention and the spirit and Scope of tho appended eiainis.
